Even with your windows and doors shut, your house may still feel drafty in the winter and like a sauna in the summer. If your roof isn’t the problem, then you might need to replace your old windows and doors. Let’s take a look at how doing so will give you a more energy-efficient home and lower your energy bills too.
You might be surprised at the engineering that has improved the energy efficiency of modern windows, saving you between 7 to 15 percent on your energy bills. It all comes down to heat gain and loss as well as how much sunlight gets through your window.
Let’s start with your options for glass. You can choose different types of coatings that will substantially reduce heat loss, according to the Department of Energy. Or you can try heat-absorbing tinted windows, which reduce the solar heat transmitted through the glass.
Another option is double-pane or triple-pane windows, which are hermetically sealed with air – or an inert gas like argon or krypton – in between the panes of glass to deter heat flow.
But it’s not just the glass that adds energy efficiency. Choosing the proper framing materials, such as vinyl or fiberglass, will ensure your windows conduct less heat into your home. Both have air cavities that can be filled with insulation, while metal and wood frames do not.
When you’re evaluating new windows (and doors, too), you’ll see they come with ratings such as R-Values and U-Values. An R-Value measures the ability of a material to resist heat flow. The higher the value, the better the insulation. The U-Value, on the other hand, measures the ability of a material to conduct heat. In that case, the lower the number is, the greater the energy efficiency.
Doors aren’t just made of wood anymore. These days, you can purchase fiberglass or insulated steel doors. A door of this material, with no window and measuring one and half inches thick, actually provides five times the insulation you would get with a wood door of the same size, according to the Department of Energy.
Of course, if you have a patio or sliding glass door, you’ve probably figured out that with all that glass, you’re losing heat. It’s also true that sliding glass doors don’t seal as well as swinging doors. But as with modern windows, you can get a sliding glass door made with several panes of glass and special coatings to improve insulation. Also, most patio doors have additional insulation between the inner and outer parts of the metal frame.
Installing new windows and doors in your home can keep out those pesky drafts and ensure your AC or heat stays right where you need it – inside your home. Andy they’ll look fantastic, too!
